Sorry, but maketfm did not succeed.
The log file hopefully contains the information to get MiKTeX going again: C:/Users/Chris/AppData/Local/MiKTeX/2.9/miktex/log/miktex-maketfm.log You may want to visit the MiKTeX project page, if you need help.

以下是 MWE：
\documentclass[a4paper,11pt]{article}
\usepackage{bbold}
\begin{document}
If $V_i = \displaystyle\sum^\infty_{n=0}\mathbb{1}_{X_n = i}$ is the number of visits to $i$, then $\mathbb{E}[V_i] = \displaystyle\sum^\infty_{n=0}\mathbb{P}(X_n=i)$.
\end{document}
答案1
您的 TeX 发行版有点过时，这导致了您的问题。请参见以下几行：
Mine system: Version 3.14159265-2.6-1.40.16 ... (preloaded format=pdflatex 2016.1.29) ...
Your system: 3.14159265-2.6-1.40.16 ... (preloaded format=pdflatex 2016.1.10) ...
% ^^
不同之处preloaded format=pdflatex 2016.1.10在于2016.1.29
因此，使用以下 MWE（为了提高可读性，我只添加了一些换行符）：
\documentclass[a4paper,11pt]{article}
\usepackage{bbold}
\begin{document}
If $V_i = \displaystyle\sum^\infty_{n=0}\mathbb{1}_{X_n = i}$ is the
number of visits to $i$, then
$\mathbb{E}[V_i] = \displaystyle\sum^\infty_{n=0}\mathbb{P}(X_n=i)$.
\end{document}
我得到以下结果，没有错误或警告：
